ZOZEN WNS series gas-fired hot water boilers are widely used in industries such as central heating, hotels, and hospitals. This series of gas-fired boilers adopts a wetback structure. The large-diameter corrugated furnace can not only effectively absorb the thermal expansion, but also increase the radiant heating area. With the advanced combustion equipment, this series of gas-fired boilerscan ensure the full combustion of the fuel, and the thermal efficiency can reach over 98%. And the WNS series boiler is a package boiler, which is fast to install and saves a lot of installation and capital investment costs. In terms of quality assurance, ZOZEN has established a strict quality management system. Each boiler needs to undergo strict quality inspection procedures to complete the final assembly.
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
In the heavy machinery manufacturing industry, the processes of smelting, pouring, and producing finished castings consume a large amount of steam. ZOZEN superheated steam boiler can meet the temperature requirements of these process.
Hebei Anguo Modern Traditional Chinese Medicine Industrial Park takes modern Chinese medicine and healthy food as the leading industriies. The industrial clustering advantages and perfect infrastructure conditions have attracted many enterprises such as Tong Ren Tang, Tasly and China National Traditional Chinese Medicine Co., LTD. The concentrated supply of high-quality steam provides sufficient heat for the drying, extraction and stewing of traditional Chinese medicines. Therefore, these enterprises have strict requirements on the performance in various aspects of steam boilers.
ZOZEN has always been committed to continuously improving the thermal efficiency of gas-fired boilers. WNS three-pass condensing gas-fired steam boiler is an environmentally friendly boiler product of ZOZEN. With advanced low NOx burner, the boiler thermal efficiency can be as high as 98% while achieving ultra-low emission of NOx≤30mg/Nm³. After the fuel is fully combusted in the large-diameter corrugated furnace, the high-temperature flue gas flows backwards to the second pass along the furnace through the reversal chamber , that is, the threaded smoke tube bundle area; After convective heat transfer, the boiler flue gas temperature gradually decreases and goes to front smoke box and turns to 3rd pass, that is, the smooth tube bundle area; Finally, the flue gas enters the economizer and condenser through the rear smoke box, and flows into the chimney and is exhausted into the atmosphere.
Sichuan Energy Investment has always formed a profound cooperation with ZOZEN. As an important window for opening up to the northeast of China and participating in the international specialization, Suifenhe has developed into a large-scale Russian wood import and distribution center. With the rapid development of the wood import and export processing industry, the ZOZEN SZL series biomass steam boiler project was installed here, providing concentrated steam for wood drying of wood processing enterprises in the Sino-Russian trade zone.
In the R&D and production process of medical materials, sterilization and disinfection processes have put forward high requirements on temperature. The boiler can be said to be the indispensable important equipment in the medical industry. Nantong Kedi Medical Material Co., Ltd. is a professional company specializing in the research and development of medical materials such as dressings, designer materials, disposable medical consumables and surgical hygiene products.
Founded in 1958, Changchun University of Science and Technology has three campuses with a building area of 627,000 square meters and a total of 29,820 students. Therefore, the boiler plays a non-negligible role in ensuring the daily needs of teachers and students.Facing the severe situation of environmental protection, Changchun University of Science and Technology decided to upgrade the original boilers. ZOZEN won the trust of Changchun University of Science and Technology with its advantages o...
